I'm thinking Pirelli Scorpion XC MH for the front and the Kenda K760 for the rear. The Kenda is almost the same tread pattern as my Bridgestone M402 but is cheaper and DOT rated. I can't find my Bridgestone front any more. KTM now stocks my bike with Dunlop GEOMax MX51s FR and RR, but not sure I'm that interested right now with all the suggestions above.
